Main uses: sheet metal work, putty, polishing, surface treatment 
 Features: Chassis is rectangular in shape, can be done only before and after the reciprocating motion. A drive wheel produced by the wing rotary motion into reciprocating motion by the cam so that the chassis to do before and after exercise, and replace the wing with the piston front to back wheel so that the reciprocating motion of the two chassis. (Only 8200,8200 D) There is also the type of use of the exhaust cleaning (the name behind the "D" symbol) 
 Advantages: Suitable for grinding straight portion of the putty, a profile (along the lines of grinding), are primarily for straight-line part of the grinding operation. Ultimately had to use putty by hand, but it can be used to replace manual work grinding machine grinding machine vibration. Very hard over the past putty material, the use of more types of stroke 20mm mainframe (such as the 8200 series), but recent soft putty material gradually increased, so its corresponding stroke is 5 ~ 6mm aircraft types also increased. 
 8150C: the use of glass fiber chassis, the use of lightweight design, easy to operate. (Weight 1.4kg) The use of pneumatic motor D / A grinding machine, etc., can achieve low vibration. 

 Parameters: speed (stroke7000 r / min), air consumption (350l/min), working pressure (0.4 ~ 0.6MPa), vibration size (stroke 6mm), chassis size (74 * 175), Dimension (W * H * L: 74 * 87.5 * 288), noise (90dBA), the inlet aperture (G1 / 4 "), Weight (1.4KG), packaging (10 units / box).
